Good to know, this is where I saw it--

Even if you use a different oil the SFR additive such as gas-zol is a great additive in the turbo system, it will eliminate the chance of wear even when the sled is shut off and the turbo is spinning without the a oil supply pumping.
My turbo oil looks better than it ever has with around 300miles on this change,
I have also been running the 2 stroke and could swear I get away with a higher boost levels on low octane but that could be dependent on other factors. I have ran it for around 300miles and pulled the PV and they came out easy and you can see shinny metal spots on the PV still, no build up at all, (not to say it wouldn't look the same with other oils, just saying what I have found so far) The pistons and cylinders also look perfect, I think it has a total of 2200miles.
If nothing else I think running it in the turbo oil system, chain cases, DD's, etc... is a huge benefit. just add 1oz per court of the appropriate additive. SFR has the same weight as water so water can't displace it if it ever enters the system.
BTW, a guy stopped buy the other day driving a 94 jeep that has 168000 miles on a V8 and had a rod knocking, so he put some additive in and then comes back inside and says, "it sure made it quieter than it was so it must have helped a little" I just laughed, but that was a month ago and I still see it on the rode, I don't expect it to be going much longer.
